Template Easy Charts

[billy_hanner]

Hi,

Has anyone had any luck using an easy chart as part of a template, we are developing a system with a process that requires a chart and the only part we haven't managed to make dynamic so far is the chart. specifically the tag history pens.

Has anyone had any luck making this work?

Thanks in advance

I did see you can do and I've done it for various other bits e.g. alarm configuration. But I can't find an easy way to create a dataset in a UDT where i can dynamically update the dataset cells e.g. if i want to add a new pen to all the charts i only have to change one UDT and all the instances will have the new history pen etc

Blegh. No, don't try to maintain the dataset in the UDT. It has to have instance-specific content, so needs to be generated. As a UI behavior, I would just keep this config in the template.

See this topic for some ideas:

Pass tag history path to easy chart popup

Good morning, in the pages of my project I have some process variables (usually float number) and all of them are historicized into the database.

All the other settings of the trend will be always the same (colors, axes ecc). I guess I could make it adding a custom property wh…
